Pariyāyasutta

Suttapiṭaka · Saṁyuttanikāya · Mahāvaggasaṁyutta · Vol. 19 · Section 566

[566] Bhikkhus, whatever equanimity (upekkhā) there is regarding dhammas internally, that too is the equanimity factor of awakening (upekkhāsambojjhaṅga); whatever equanimity there is regarding dhammas externally, that too is the equanimity factor of awakening. Thus what comes up in the summary as "the equanimity factor of awakening" becomes, by this method of exposition, twofold.
